Insert the long plastic core cover into channel of “U”-shaped
section of tunnel support. Insert the short plastic core cover into
channel of straight section of tunnel support.
4D
Turn over assembled tunnel and insert plastic core covers of
assembled tunnel between frame posts and lip on flap opening of
exterior frame (frame without the flap). Tunnel support should be
facing up.
Optional:
Use duct tape in the corners of core
covers to help secure in place and to improve
weather resistance.

Install Pet Door
5A
Optional:
If the door cut-out thickness
(T)
is 1” (25mm) or
more, insert the screw guides into the screw holes on the backside of the
interior frame (frame with flap and 4-way lock). The screw guides help
guide the screws through the screw holes from the interior frame to the
exterior frame.
Before putting away your jigsaw, place the interior frame (frame
with flap and 4-way lock) inside the cut-out and check the fit. Then
place the exterior frame (with assembled tunnel if needed for your
installation) into the underside of the cut-out to check the fit. If the frames
do not fit inside the opening, you may need to recut opening before
proceeding with installation.
5B
Before installing the pet door, you need to determine which screw
length is needed for your installation. Depending on your door thickness,
the screws may need to be trimmed with a hacksaw or screw cutter. If
the screws are too long, the finishing plugs will not fit. Use the Screw
Selection Guide
(Chart 2)
to select which screw to use and if it needs
to be trimmed for your installation. To trim screw, insert binder post
onto end of screw to protect thread. Using the binder post as a guide,
cut screw to correct length with a hacksaw. After cutting to length,
remove the binder post to clean screw threads. Repeat process with
remaining screws.
